MUSlC-LEAFTURNER.

SPECIFICATION forming part of Letters Patent No. 279,737, dated June 19, 1883.

Application filed February 14,1883. (ModeL) To all whom itmay concern:

Be it known that we, AMos T. FOX and DANIEL T. Fox, of Mount Pleasant, in the county of Vvestmoreland and State of Pennsylvania, have invented a new and Improved Music-Leaf Turner, of which the following is a full, clear, and exact description.

Our.invention consists of wire frames or fliers-pivoted on the board of the musical instrument, usually employed for holding'the music, or on a specially-provided board or frame, and contrived for application of sheet or book music, with pawls arranged for turning the sheets both ways by means of pull wires or cords to be worked by a foot-treadle or other device, and a spring for retracting them, and also for causing them to hold the wire frames down when turned, all as hereinafter fully described.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of our improved music-turner, showing it in front view with a music-sheet applied to it. Fig. 2 is an elevation of the same in back view. Fig. '3 is a section on line 00 m, Fig. 2. Fig. 4 is a perspective front View of the turner in modified form. Fig. 5 is a plan view of one of the wire frames or fliers.

Ve make wireleaf frames or fliers for turn ing the music-leaves by bending small wires into the rectangular form represented, and-being shown separately in Fig. 5, of which a. represents the axial part; b, pivots; c, offsets through which to pass the music-leaves; (7, arms; 0, crossbars, and f, push-studs; and we pivot the fliers to the board or frame by staples h for the pivots, in which the pivots are to be sufficiently slack to allow the fliers to lieflat on each other; and we also employ a larger staple, i, at the lower end of the board, for a guide to the push-studs f when subject to the pawls j, by which the fliers are pushed over from side to side of the board or frame. These p. wls have notches It, by which they engage the push-studs f, and they extend through slots 1 of plates at into chambers a in the base of the board or frame, wh ere they connect with I the end of a bow-sprin 0, arranged in a recess, p, in the board, or in the space within from falling.

for the pawls on the pushing side to lift the one on the falling side, so that it will not bear on thepush-stud of the frame and prevent it that the ends will project past the edges of the leaves of the music, and thus will not fall on them. The pawls have an extension, at, be-

yond the pivot c, which extends into a guideslot, 1), cut in or through the edge of the bottom board, to further steady the action, the

said pawlextensions a being thrust against the end wall of the recess by the spring 0, to cause pressure by the pawls on the push-stud f when the frames lie in their positions to keep them down.

Thepull-wires q may be arranged singly, as in Figs. 2 and 3, in guide-staples WV, or they may be double, as in Fig. 4, one member be ing above the lower frame-barand passing through the side bars, and the other member below the lower frame-bar, so that they hold each. other in placeto some extent, and do not require the staples. In the arrangement of Fig. 4. the spring and the axial wires may be connected at the middle of each, or there about, by a ring, 00, for supporting each other. The arm d, on which the forceof the pawls mainly takes effect in. turning the fliers, may

be Ire-enforced by overlapping the end portions of the wires of which the frame is made, as represented aty.

The fliers may have spring-clips a fitted on them at the corners, as shown, or in any ap proved way, for fastening the corners of the leaves of music, and fine wires 1) may be stretched across the fliers from one arm to the of a book'may be arranged in the fliers suit- These extensions of the pawls are bent down toward the frame or board, so

ably for being turned by them as well as separate sheets, and by the arrangement of the pivots b loosely in the staples h the number of fliers that may be arranged and properly worked together will be ample for any requirements, whether for music, lectures, or sermons, the wires being fine.

Itwill. be noticed. that the contrivance of one spring to operate both pawls, and also to hold the fly-frames down after being turned, simplifies the apparatus and lessens the nunt her of parts, as well as chcapens the cost.

The staples c are employed to rest the music on at the lower end.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. The combination, in a music-lcaf turner, of rectangular wire fly-frames having pivots b, push-studs f, offsets 0, arms (1, and crossbar (a, turningpawlsj, and a spring and pull wires, substantially as described.

2. The lly-frame of a music-leafturner, made of wire and bent at one corner to form a pivot, I), push-stud], and offset 0, as shown and described.

3. The guard-staple 1', in combination with the pivoted fly-frames having push-studs f, and with the pushpawls j, one or both, substantially as described.

4. The combination, in a music-leaf turner, ofl'ly-iramcs pivoted on a board or frame, a pair of push-pawls, j, and pull-wires for turning said fly-frames forward and backward, and a retracting-sprin g for the pawls, substantially as described.

5. The combination, with the pawls j, of the slotted plates on, the board having chambers n and recess 1), the bow-spring 0, and the pullwires q, whereby the pawls may be operated as described.

6. The combination, in a music-leaf turner, ofa bow-spring, 0, located in the recess or space in the frame, with the pawlsj of the ilyframes, arranged for t-nrnin them forward and backward, the said spring being connected at its ends with the pawls, respectively, substantially as described.

7 The pawlsj, arranged with the i1 y-fra1nes, and connected with the spring, and provided with stud 7!, arranged with'relation to pivots 1: and the wall of the frame, for pressing the pawls on the frame and holding them down when turned, substantially as described.

8. The combination, with the itlyl'i.'amcs, of pawls j, for turning them in opposite directions, said pawls having extensions s, crossing each other, and provided with guards l for .lilt ing the pawls from the 'l'alling frames, spbstanti al ly as described.

9. The combination, with the lly-l'rames, ol' pawls j, extended and crossed, the extensions being curved to prevent contact with the music-leaves, substantially as described.
